IMPORTANT SAFETY INFORMATION
NOTICE
Units are voltage-specific. Refer to specification label
for electrical requirements before beginning installation.
Connecting unit to incorrect power supply will void
product warranty and may damage unit.
This unit is intended for commercial use only — NOT for
household use.
Do not turn on power to unit until holding vessel has been
filled with water. Dry operation may cause element burnout.
Always drain holding vessel with power to unit off or
element burnout could occur.
Do not use excessive force when tightening unions or
nuts. Over-tighening and excessive force may cause leaks.
Incoming water in excess of 3 grains of hardness per
gallon (GPG) (0.75 grains of hardness per liter [GPL])
must be treated and softened before being supplied to
water heater(s). Water containing over 3 GPG (0.75 GPL)
will decrease efficiency, increase energy use, and reduce
operating life of unit through increased lime build-up.
Product failure caused by liming or sediment buildup is
not covered under warranty.
Use only delimers that are non-corrosive to aluminum,
brass, and stainless steel. Damage to unit caused by
corrosive materials is not covered under warranty.
Inspect unit regularly for lime and sediment buildup.
Excessive buildup may affect performance and reduce
operating life of unit. Unit failure due to lime or mineral
deposits is not covered under warranty.
NSF Criteria
NSF Standard 4 has recently added performance requirements
for food rethermalizing. The requirements mirror the
requirements for food rethermalizing in the FDA Food Code.
The basic requirement is that food reach a temperature of
165°F (74°C) in a time period of two hours or less.
Appliances that are manufactured for the purpose of
rethermalizing food will need to meet these performance
requirements in order to be listed to NSF Standard 4.
The Hatco FR Series heating unit is specifically made for food
rethermalizing, however, the heating unit is designed to be
incorporated into a hot water bath rethermalizer. Hatco does
not supply the vessel that contains the water, nor the system
which determines how food is placed and held in the vessel.
The Hatco FR unit attaches to the bottom of the vessel and
supplies hot water to the vessel.
Hatco does supply sizing recommendations to enable the
appliance manufacturer to correctly size the FR unit to the
vessel. However, there are variables in the way that the
vessel is manufactured that affect its ability to pass the NSF
performance requirements. The Hatco FR unit is listed with
NSF for construction only. Due to the fact that the FR is only a
portion of a larger system, it is impossible to do performance
testing until the FR unit is incorporated onto the water vessel.
It is the responsibility of the vessel manufacturer to have the
entire rethermalizing appliance tested and listed in accordance
with NSF Standard 4. Simply hanging an NSF listed FR unit
on the appliance does not transfer NSF listing to the entire
appliance.
